fly in no way resembled the very long black and white ones of the ichneumon. 

 The fly, however, held up its black and white legs, applying their bases to its 

 head and moving them so that they closely resembled the antennae ol the 

 Hymenopterous insect in movement as well as in colounng and proportions. 

 Another species of fly possessed true antennae which were remarkably long tor 

 this order and thus closely resembled those of an ichneumon. 



With few exceptions, the whole of the material here briefly described may be 

 seen in the Hope Department of Zoology, Oxford University Museum.
